Obj-C on Linux

[font=monaco,courier]find /usr/lib -type f -name '*.so' | xargs nm | grep objc_lookup_class[/font] will at least tell you if any of the libraries in /usr/lib define objc_lookup_class. Probably also worth running a similar command on /usr/GNUstep/System/Libraries .

Because even when you've only got one source file, it's quicker to type make than it is to type gcc -g -c -Wall -W -Wno-unused-parameter -Werror -Os -I/usr/X11R6/include main.c; gcc -o Executable main.o -L/usr/X11R6/lib -lGL -lGLU -lglut -lX11 -lm, and when you've got more than one file keeping track of dependencies and what needs to be rebuilt makes such a huge improvement to compile times that it's pointless to avoid the makefile...
